Can someone give me a detailed description about Information Systems?

<p>I am interested in majoring in IS but every website I go to only gives me a very general description about the major.</p>

<p>Every school seems to focus on different things in IS.</p>

<p>Can anyone give me a good summary about this major?
What do you do?
What is it about?</p>

<p>It's a fushion of technology and business right?</p>

<p>I'm interested in Carnegie Mellon, Emory, UMD.</p>
